This learning module, one of a series of 127 performance-based teacher education (PBTE) learning packages focusing upon specific professional competencies of vocational teachers, deals with using reinforcement techniques. Various aspects of the technique of reinforcement and its use are discussed, including positive reinforcement, negative reinforcement, extinguishing, verbal and nonverbal cues, and use of various instructional materials and approaches to strengthen learning. The module consists of three learning experiences that (1) present vocational teachers with information about reinforcement theory and techniques, (2) allow the teachers to use the techniques in a simulated classroom experience, and (3) require them to apply the techniques in an actual teaching situation. Each learning experience includes some or all of the following: an enabling objective, an information sheet, one or more learning activities, a feedback exercise, model responses to the feedback activity, and one or more reinforcement checklists.
